2014-02-01	Build/install manual	Eelco Dolstra

2014-01-21	Fix build	Eelco Dolstra

2014-01-09	Handle systems where "echo -n" doesn't work	Eelco Dolstra

2013-11-25	Expand configure variables before writing config.status	Eelco Dolstra
	This way, we can use config.status for generating scripts/* (without ending up with lines like "#! /usr/bin/perl -I${libexecdir}/...").
2013-11-25	Remove obsolete setting of $CC_FOR_BUILD	Eelco Dolstra

2013-11-25	Don't install Libtool	Eelco Dolstra

2013-11-25	Don't instantiate Automake makefiles	Eelco Dolstra

2013-11-22	Drop the dependency on Automake	Eelco Dolstra

2013-11-22	New non-recursive, plain Make-based build system	Eelco Dolstra

2013-11-14	Remove nix-setuid-helper	Eelco Dolstra
	AFAIK, nobody uses it, it's not maintained, and it has no tests.
2013-08-19	Turn on -Wall	Eelco Dolstra

2013-08-07	Run the daemon worker on the same CPU as the client	Eelco Dolstra
	On a system with multiple CPUs, running Nix operations through the daemon is significantly slower than "direct" mode: $ NIX_REMOTE= nix-instantiate '<nixos>' -A system real 0m0.974s user 0m0.875s sys 0m0.088s $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m2.118s user 0m1.463s sys 0m0.218s The main reason seems to be that the client and the worker get moved to a different CPU after every call to the worker. This patch adds a hack to lock them to the same CPU. With this, the overhead of going through the daemon is very small: $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m1.074s user 0m0.809s sys 0m0.098s
2013-08-06	Set the default GCC optimisation level to -O3	Eelco Dolstra

2013-07-12	Add gzip support for channel unpacking	Gergely Risko

2013-03-25	makeStoreWritable: Use statvfs instead of /proc/self/mountinfo to find out ↵	Shea Levy
	if /nix/store is a read-only bind mount /nix/store could be a read-only bind mount even if it is / in its own filesystem, so checking the 4th field in mountinfo is insufficient. Signed-off-by: Shea Levy <shea@shealevy.com>
2013-01-02	Urgggh	Eelco Dolstra
	http://hydra.nixos.org/build/3661100
2012-11-15	Disable use of vfork()	Eelco Dolstra
	vfork() is just too weird. For instance, in this build: http://hydra.nixos.org/build/3330487 the value fromHook.writeSide becomes corrupted in the parent, even though the child only reads from it. At -O0 the problem goes away. Probably the child is overriding some spilled temporary variable. If I get bored I may implement using posix_spawn() instead.
2012-11-09	Use vfork() instead of fork() if available	Eelco Dolstra
	Hopefully this reduces the chance of hitting ‘unable to fork: Cannot allocate memory’ errors. vfork() is used for everything except starting builders.
2012-10-10	Out-of-tree building of perl modules.	Mats Erik Andersson

2012-10-03	Rename nix-worker to nix-daemon	Eelco Dolstra

2012-10-03	Remove bin2c	Eelco Dolstra

2012-09-14	Test whether GNU tar understands --warning=no-timestamp	Eelco Dolstra
	http://hydra.nixos.org/build/3031618
2012-08-27	Whitespace	Eelco Dolstra

2012-08-01	Use a GNU tar flag to shut up warnings about implausibly old timestamp	Eelco Dolstra

2012-07-26	Merge branch 'master' into no-manifests	Eelco Dolstra

2012-07-23	Handle platforms that don't support linking to a symlink	Eelco Dolstra
	E.g. Darwin doesn't allow this.
2012-07-23	Use lutimes() if available to canonicalise the timestamp of symlinks	Eelco Dolstra
	Also use utimes() instead of utime() if lutimes() is not available.
2012-07-09	Add WWW::Curl as a dependency	Eelco Dolstra

2012-06-29	Use XZ compression in binary caches	Eelco Dolstra
	XZ compresses significantly better than bzip2. Here are the compression ratios and execution times (using 4 cores in parallel) on my /var/run/current-system (3.1 GiB): bzip2: total compressed size 849.56 MiB, 30.8% [2m08] xz -6: total compressed size 641.84 MiB, 23.4% [6m53] xz -7: total compressed size 621.82 MiB, 22.6% [7m19] xz -8: total compressed size 599.33 MiB, 21.8% [7m18] xz -9: total compressed size 588.18 MiB, 21.4% [7m40] Note that compression takes much longer. More importantly, however, decompression is much faster: bzip2: 1m47.274s xz -6: 0m55.446s xz -7: 0m54.119s xz -8: 0m52.388s xz -9: 0m51.842s The only downside to using -9 is that decompression takes a fair amount (~65 MB) of memory.
2012-05-10	Support building with the Perl XS bindings disabled	Eelco Dolstra
	Since the Perl bindings require shared libraries, this is required on platforms such as Cygwin where we do a static build.
2012-05-04	Require SQLite >= 3.6.19	Eelco Dolstra
	Nix needs SQLite's foreign key constraint feature, which was introduced in 3.6.19. Without it, the database won't be cleaned up correctly when paths are deleted. See e.g. http://hydra.nixos.org/build/2494142.
2012-04-13	If "pv" is available at compile time, hard-code its path	Eelco Dolstra

2012-03-19	Fix the optional dependency on OpenSSL	Eelco Dolstra
	http://hydra.nixos.org/build/2306540
2012-03-18	Drop the externals directory	Eelco Dolstra
	Nix now requires SQLite and bzip2 to be pre-installed. SQLite is detected using pkg-config. We required DBD::SQLite anyway, so depending on SQLite is not a big problem. The --with-bzip2, --with-openssl and --with-sqlite flags are gone.
2012-02-15	On Linux, make the Nix store really read-only by using the immutable bit	Eelco Dolstra
	I was bitten one time too many by Python modifying the Nix store by creating *.pyc files when run as root. On Linux, we can prevent this by setting the immutable bit on files and directories (as in ‘chattr +i’). This isn't supported by all filesystems, so it's not an error if setting the bit fails. The immutable bit is cleared by the garbage collector before deleting a path. The only tricky aspect is in optimiseStore(), since it's forbidden to create hard links to an immutable file. Thus optimiseStore() temporarily clears the immutable bit before creating the link.
2012-01-11	* Figure out the extension of dynamic libraries; don't hard-code .so.	Eelco Dolstra

2012-01-05	* Add a -I flag to the Perl bindings to nix-build and some other	Eelco Dolstra
	scripts. * Include the version and architecture in the -I flag so that there is at least a chance that a Nix binary built for one Perl version will run on another version.
2012-01-04	* Let --disable-gc work.	Eelco Dolstra

2012-01-03	* Add a test for nix-channel.	Eelco Dolstra
	* Refactor the nix-channel unpacker a bit.
2011-11-21	* Doh.	Eelco Dolstra

2011-11-21	* Put back the "sys_name" variable which got removed somewhere. This	Eelco Dolstra
	broke building on Cygwin and Solaris.
2011-11-21	* Escape the [ and ] characters in the sed call, otherwise autoconf	Eelco Dolstra
	will eat them.
2011-11-20	* "sed" on FreeBSD doesn't know the "+" operator.	Eelco Dolstra

2011-11-18	* In the platform, canonicalise "amd64" to "x86_64". FreeBSD 8.2's	Eelco Dolstra
	uname reports amd64. * Drop the FreeBSD version number, e.g. "i686-freebsd" instead of "i686-freebsd8.2".
2011-11-16	configure: Change i*86 to i686 as has always been done.	Ludovic Courtès

2011-11-16	configure: Rely on `AC_CANONICAL_HOST' to determine the Nix system name.	Ludovic Courtès
	This should be more robust and also plays better with cross-compilation---it uses the host name, instead of using the build name.
2011-11-07	* Boldly make SQLite WAL mode the default again. Hopefully the	Eelco Dolstra
	intermittent problems are gone by now. WAL mode is preferrable because it does way fewer fsyncs.
2011-10-10	* Install NixManifest.pm, NixConfig.pm and GeneratePatches.pm under	Eelco Dolstra
	the Nix:: namespace.
2011-10-10	* Include the Nix Perl bindings in Nix itself. This will allow the	Eelco Dolstra
	bindings to be used in Nix's own Perl scripts. The only downside is that Perl XS and Automake/libtool don't really like each other, so building is a bit tricky.
2011-07-13	* Show the default for --with-store-dir (Nix/211).	Eelco Dolstra
